Control method and device for multimedia meeting

Abstract

The present invention provides a control method for multimedia meetings. The method comprises the steps of receiving an indication of controlling the use of media playing resources by assigned meeting participants, wherein, the indication is sent by a service control entity; the indication being carried by the service control entity through a session initiation protocol (SIP); controlling the use of media playing resources by assigned meeting participants according to the indication. The present invention also provides a control device of multimedia meetings and a SIP signaling control device. The technical scheme of the present invention is convenient for the meeting participants having a multimedia meeting control right to control the multimedia meetings.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control method and device for a multimedia conference. Background technique [0002] The next-generation network based on the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) allows users to organize multimedia conferences such as audio conferences, video conferences, and data conferences. Multimedia conferences are usually implemented by instructing a multimedia resource function (MRF, Multimedia Resource Function) entity executes the conference control logic, such as creating a conference, controlling conference participants to join or exit the conference, inserting media information for a conference participant, inserting media information for the entire conference, conference control authority authentication, etc., so as to provide media for the conference Conferencing services for mixing, transcoding, notification of party joins, and more. In practical appli...

Problems solved by technology

[0015] in such as figure 2 In the process shown, although the service control entity can carry the conference attribute through the SIP message body such as the Info message, instruct the MRF to provide conference services such as media stream insertion and conference joining notification for the entire conference or for a single conference participant, but due to the current There is a Mr interface protocol. For example, the instruction sent by the service control entity to the MRF only generally describes the occupancy rules of the conference participants for media playback resources. Therefore, it is difficult to use the control of the service control entity on the MRF to further control each MRF. The use of media playback resources by a conference participant, such as not wanting to hear the speeches of user A corresponding to user equipment A, but if the volume at user A is loud enough to allow user A to occupy the mixer, then in a similar situation , it will be difficult to use the conference server to control the multimedia conference

In addition, for the media information provided by the network side that does not have self-control capabilities, such as the media stream provided by the content server on the network side, it is impossible to control the occupation of media playback resources by the media stream through the conference server. As a result, it is difficult to effectively control the occupation of media playback resources by media streams, and the playback of media streams occupies the media playback resources required for the conference, which affects the effect of the entire multimedia conference.
